Converting Old Testament years (360 days a year) into solar years (365.24 days a year)

Daniel 12:11 King James Version:
11 And from the time that the daily sacrifice shall be taken away, and the abomination that maketh desolate set up,
there shall be a thousand two hundred and ninety days. Daniel 12:11

OT prophetic years of 1290 times .9857 = 1271 solar years.

The Babylonians occupied Jerusalem in 586 B.C.,
destroyed the Temple, and sent the Jews into exile.
586 B.C.
1291 O.T. Years
685-705 AD
The Muslim Dome of the Rock was built on the Temple Mount 685 - 705 AD
Take 705 AD as the year for the Dome of the Rock and add 586 and you get 1291.

Daniel 12:12 King James Version:
12 Blessed is he that waiteth, and cometh to the thousand three hundred and five and thirty days. Daniel 12:12

1335 times .9857 = 1316
1948 (when Israel became a nation) minus 1316, brings us back to another date the God of prophecy wants us to be mindful of.
That equals 632 AD , the date that Muhammad of Islam died.
